A seaplane crashed into Long Lake near Kingston, Ontario, after an engine failure during a survey flight, resulting in injuries to both occupants and the destruction of the aircraft.

What happened

The incident occurred while the crew was conducting a survey flight over the region north of Kingston, Ontario. During the mission, the aircraft experienced a sudden loss of power when the engine failed. The pilot subsequently lost control of the seaplane, which descended into Long Lake, located approximately 65 kilometers northeast of Kingston. Upon impact with the water, the airframe was destroyed. Both individuals on board sustained injuries in the crash.

Findings

The official investigation identified engine failure as the primary cause of the accident. This mechanical malfunction led to a total loss of thrust, which resulted in the pilot's inability to maintain control of the aircraft and its subsequent impact with the lake surface.
